- Abstract:
-
The design treatment capacity of an wastewater treatment plant (WWTP) in Zhaoqing is 3×104 m3/d, and the effluent water quality is required to meet the first level A standard of Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). The application of BioFIMag process based on pure MBBR solved the problems of limited footprint and short construction period of the project. Through high-density biofilm area, enhanced biofilm water separation area and loading an intelligent control system, the effluent quality always could meet the discharge standard, and accurate operation of the WWTP was realized. After the implementation of the project, the actual footprint of the WWTP was only 0.067 m2/(m3·d-1). It took only 30 days to complete the design, construction and commissioning of the project. The concentrations of COD, NH4+-N, TP and SS in the effluent were 13.07 mg/L, 1.47 mg/L, 0.26 mg/L and 2.83 mg/L, respectively, which were better than those of first level A standard. The power consumption of the project was 0.203 kW·h/m3. PAC was used as coagulant for phosphorus removal, and the molar ratio of Al and the removed TP was 2.1. The direct operational cost was 0.168 yuan/m3. The BioFIMag process has the advantages of extremely small footprint, efficient treatment, ultra fast implementation, economic saving and simple management, which is suitable for the implementation of new wastewater treatment projects.
